An electrical outlet has two vertical slots and a hole into which a three prong plug may be inserted. the maximum potential difference between the two vertical slots is 120 volts. the hole is connected to earth ground. estimate the maximum electric field that exists between the two vertical slots.

maximum electric field E is 9200 V/m

Explanation:

Given data

maximum potential difference V = 120 volts

to find out

maximum electric field E

solution

we know that here vertical distance always 1.3 cm = 1.3 × m

and potential difference is

V = E× distance

now find E  by put all value

E = V /  distance  

E = 120 / 1.3 ×

E = 9200

so maximum electric field E is 9200 V/m

show the diagram then i will answer

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
